WHEEL FOR MOTOR-VEHICLES.

Specification of Letters resent.

, Patented Nov. 17, 1908.

To all whom it may concern:

' Be it known that I, ALDEN L. McMURTRY, a citizen ofthe United States,residing in the borough of Manhattan, city, county, and State of NewYork, have invented certain Improvements in Wheels for Motor-Ve hicles,of which the following is a specification.

This invention relates to a class of wheels having elastic or pneumatictires carried by a wheel rim that may be removed from the felly or rimbase of the Wheel, and comprises the new organization hereinafter setfortiTin detail.

In the accompanying drawings: Figure 1 is a transverse section throu hthe tire and wheel rim on the line 1, 1, o Fig. 2; Fig. 2 is a Viewpartly in elevation and partly in longitudinal section.

a are spokes and b the felly to which is applied a metal tire plate orrim base 0 flanged at the sides to embrace the sides of the felly andattachedthereto by bolts or screws such as d. At suitable intervals andbetween each air of adjacent spokes if desired, the felly is ormed witha recess 6, within which is arranged a rotating shaft f, the outer endof which passes through the flange of the rim base 0 and is squared forthe reception of a suitable key. Its inner end is mounted in a bearing 9which may be, and which as shown is, attached to the inner side of therim base 0. Keyed .to the shaft is a locking arm 71 which passesradially beyond the circumference of the plate 0 through an elongatedslot in the latter. The removable wheel rim 2' is integral andcontinuous and has rolled in it a continuous circumferential corrugationj of considerable height forming in the inner face of the rim a lockingchannel into which the locking arms h are swung by rotation of the boltsf and in which they fit tightly with frictional contact. The recess e inthe folly and the slot in the rim base are so arranged that the lockingarms k may be swung to disengage the rim in a direction opposite to thatin which the tire will.have a tendency to creep; and the creepingtendency of the tire tending to carry the locking plates further in thedirection in which they have been I swung to engage the rim will causethe arms to abut against the end wall of the slot in the rim base. Toprevent the locking arms from being disengaged from the rim by vibrationor motion of the wheel, the inner end of the arm may be flat and engagedby a stiff flat spring is, the reaction of which tends to hold the armupright or in radial position.

I claim: 1. A wheel comprising a felly recessed i its outer face, aremovable wheel rim formed with a longitudinal locking recess in itsinner face, a pivoted rim locking device seated in the recess in thefell and adapted to be moved from a tan ential to a radial position toengage the locking channel in the rim.

2. A wheel comprising a felly having'a recess in its circumferentialface, a continuous integral metal wheel rim having in it .a continuouscircumferentialcorrugation forming a locking channel in the inner faceof the rim, and a rim locking device seated in the recess in the fellyand adapted to be moved outwardly from a tangential position to engagethe locking channelin the rim.

3. A wheel comprisin a fell recessed in its outer face, a removab e wheerim formed with a longitudinal locking recess in itsinner face, apivoted rim locking'device seated in the recess in the fell and adaptedto be moved from a tangentia to a radial position to engage the lockingchannel in the rim, and resilient holding means for said locking dev1ce.

4. A wheel comprisin a fell recessed in its outer face, a removab e wheerim formed with a longitudinal locking recess in its inner face, apivoted rim locking device seated in the recess in the folly and adaptedto be moved radially beyond the circumference of the felly to en age thelocking channel in the rim, and resi ient holding means for said lockingdevice.

In testimony whereof. I have hereunto subscribed my name.
